Fix for PPM tizen sample build issue.

Fix for PPM tizen sample build issue.

PPM service files were building without TIZEN related macros as the
definitions were added only for CFLAGS. Modified the code for adding the
definitions to CCFLAGS so it will be added for compiling .c and .cpp
files.

Fixed the compilation errors getting in tizen ppmsample application.
